As for the weapon itself, it is awesome. I don't generally like curved/eastern swords but it looks okay, and it wields like a real two handed sword should. I mean real ones weighed in the neighborhood of 10 pounds and it strikes fast like a two handed sword should because you have two hand to generate speed and power. Now that she has all the sould need to fill it, she just runs around flailing with abondon, and I have started to just unequip her cuirass just for fun. It might be overpowered.
So did they mean it to be like it is or did they screw it up as well?

I've killed 10 people who trust me, which is the magic number to fill the sword to it's fullest but it still reads a 33 hit damage in the inventory menu and it doesn't seem to do anything extra then it did when I first found it??? Not a big deal, was just hoping to add to my traveling arsenal
The weird thing is that the daedric prince ( the name eludes me at the moment ) that made the blade spoke to me and told me that it was at it's full strength, what's the change supposed to read in the inventory menu, or is it even visible?
The ebony blade from Oblivion is still my fav. between the two.
